I recently received the iTSX from you and decided to Install it yesterday. I've tried to get it working all day with no luck. I have the most current version of the software and am still getting nowhere. It gets part way through and stops. Then says my vehicle is unsupportable. I know it is a long weekend, but I'm looking for some help. Any advice?

Earlier tonight I ran into a problem when running the SCT Device Updater to get updated FW and tune version. Program would hang... there was no movement on the status bars at bottom of the SCT Device Updater panel labelled "Starting update" and "Loading Firmware". I just found a way around the problem. When program hung, I closed the program (clicked on X in upper right corner)... then restarted program. Found there was some progress on the status bar (green), then the program would freeze again. Program was closed again, then restarted. Some more progress was made, but it would freeze again. After going thru the closing & re-starting the Updater program 4 times, it eventually got on track. I now have the latest FW and tune version; FW 1054 & tune version 1.013GM. Think my situation was more complicated since I updated iPod to the latest Apple iOS after having initially loaded the tune on the iTSX device when iPod was at the downlevel iOS. Don't know for sure, but glad to have the latest FW and tune version now. The iTSX was a nice addition... glad the bugs were finally worked out.

Ted put me in contact with the guys from SCT. They have a work around until the firmware is updated for the 2013 Camaro. Pull the OnStar fuse. See below:

The fuse panel you need to access is behind the end of the driver’s side of the dashboard… Here is a picture with the end removed.

On our test car, we had to peel back a little of the door seal to get it completely off, so you may have to do that too. Be careful as the glue pretty sticky.

On the back side of that end cap, there is a fuse diagram sticker… We want the 7.5A ONSTAR fuse.

It’s pretty easy to locate on the fuse panel itself…
There should be a fuse puller under the hood you can use to take it out.

This fuse just needs to be out during upload and programming. Once the vehicle is programmed, you can reinsert it. Remember to only remove or insert the fuse with the key off.

This should provide a temporary solution, until we can implement it appropriately in the firmware. Even with this fuse pulled, we have seen an occasional upload failure (an issue that is getting fixed in the firmware), so I would advise trying this 2 to 3 times. Once the upload completes, downloading doesn’t have any problems, so you should be good at that point.

I only had to do this procedure once. It worked the first time.
Thank you so much Ted, Rudy and Tim!
It now runs like a BEAST!
